How can I get full link to an image in the img tag through the Html helper (image method)?

问题

I have this code snippet in an email layout:

  <div>
    <?php echo $this->Html->image('Layouts/default/Logo.png', array(
      'alt' => 'Setin SRL',
      'url' => $this->Html->url(array('action' => 'index'), true)
    )); ?>
  </div>

However this is not ok. I can get the FULL url to the website through url(array('action' => 'index'), true)

But I can't find any paramater that I can set to true for image too. Any suggestion or workaround on how can I do this?

Edit 1: Basically, I need this link: Layouts/default/Logo.png to become http://www.something.com/Layouts/default/Logo.png in the img src

回答1:

i always use

$this->Html->link($this->Html->image(...), $this->Html->url(array('action' => 'index'), true), array('escape'=>false));

I think this is what you are looking for.

<?
echo $this->Html->image(Router::url('/') . 'Layouts/default/Logo.png');
?>

回答3:

What you are looking for is probably the HtmlHelper::assetUrl function that is used in the implementation of image method:

public function image($path, $options = array()) {
    $path = $this->assetUrl($path, $options + array('pathPrefix' => Configure::read('App.imageBaseUrl')));
    ...

回答4:

$img = '<img src="http://some-img-link" alt="some-img-alt"/>';

$src = preg_match('/<img src=\"(.*?)\">/', $img);

echo $src;

I want to get the src value from the img tag and maybe the alt value
